4 Claims.

This invention relates to improvements in windows and more particularly to improvements inv windows having double hung sash.

The principal object of the invention is to provide a window having double hung sash in which simple, inexpensive and weather-tight means are provided which permit the sash to be swung about horizontal axes in addition to being raised and lowered so as to permit the sash to be swung to an angular position and provide draftless ventilation and also so as to permit cleaning of the outside of the sash from the interior of the room.

Another object of the present invention is to provide such a window in which standard sash can be used thereby avoiding the necessity of providing a specially fabricated sash.

Another purpose 4of the-invention is to provide such a window which is so formed as to eliminate the necessity of any weather stripping, the construction being such that the space between the sash and the frame is adequately protected against the entrance of air or moisture so that the necessity of additional weather stripping is eliminated.

Another object of the present invention is to i provide such a window in which all stops are eliminated, the guideways for the sash being provided by grooves in the jambs and the construction of the sash being such that the sash is readily fitted in these grooves, the usual construction of double hung sash, of course, requiring the removal and replacement of the stops'in hanging the window.

Another object of the present invention is to provide carriers between the sash and the jambs which ride in the grooves provided in the jambs and which pivotally support the window and which are of readily fabricated sheet metal construction, thereby permitting Windows having the advantages of the present invention to be proi duced at very little more cost than ordinary double hung windows.

Another object of the present invention is to provide sash which can be easily and quickly fitted in the window frames without the usual planing and trimming required in fitting ordinary window sash.

Another purpose of the present invention is to provide spring means between the sash and the two carriers for the sash which draw the carriers toward the sash and insure weather tightness and at the same time do not interfere `with the free sliding movement of the carriers in the grooves of the jambs.

Figs. 9 and 10 are two perspective views of on of the carriers for the upper sash. I

The sash are hung in a frame including a lintel I0, jambs II and sill I2. The sash slide vertically in guideways provided in the jambs II and for the purpose of the present invention each of the j ambs is provided with two pairs of vertical guideways or grooves the inner or lower sash sliding in the inner pair of grooves I3 and the outer or upper sash sliding in the outer pair of grooves I4. These grooves are provided directly in the jambs and eliminate the necessity of providing stops such as are normally employed to guide the sash in their vertical movements and to insure weather tightness. The usual stops are also eliminated across the lintel and instead the lintel is grooved, as indicated at I5, so as to receive the upper rail of the outermost sash, as best illustrated in Fig. 2.

The jambs II are also provided at their upper ends with openings in which the usual pulleys I1 are mounted, these pulleys supporting the usual sash cords or jambs of which two are provided for each sash. v

Both the upper and lower sash 20 and 2| are the usual construction and preferably made of wood, the upper sash having an upper rail 22, stiles 23 and a check rail 24 and the lower sash having an upper check rail 25, stiles 26 and a lower rail 21. The check rails 24 and 25 meet in the usual manner, as indicated in Fig. 2, when the window is closed and the sash are latched and the check rail is drawn together so as to provide a weather-tight joint.by the usual sash lock 2li.

Both the upper and the lower sash are pivotally supported between a pair of carriers which are also formed with anges which ride in the corresponding grooves in the jambs.` These carriers are identical in construction and operation except that, of course, right and left hand carriers must be provided for the opposite sides of each sash. Since in other respects the carriers are identical in construction a description of one w'ill be deemed to apply to all four and the same reference numerals are employed. Each carrier includes a channel 35 which extends the full height of the corresponding sash, the channel facing outwardly and the edges of the channel being received in the corresponding pair of grooves of the adjacent window jamb, as best illustrated in Fig. 4. One of such channels 3l)I is, of course, arranged at each side of each sash and the sash is pivotally secured to the back of` this channel by a pin 3l which extends through a hole 32 in the corresponding stileand projects outwardly from the stile and is preferably formed with a slot at its outer end so that it can be readily turned by means of a screw driver. The opposite end of the pin 3| is threaded and screws into a nut 33 which is disposed inside of the channel 35' and is fixed against turning therein in any suitable manner. As shown this nut is square and extends the full width of the channel 35 and in order to prevent the nut from dropping when the pin 3l is withdrawn the nut is contained within a holder or cage 34 which can be of any suitable form and as shown comprises a piece of sheet metal 35 the back of which is welded or otherwise suitably secured to the inside face' of the channel 3U and the edges 36 of which are bent outwardly to form retaining flangeslfor thev nut.

Means are providedrfor yieldingly holding each channel 30 in firm engagement with the face of the corresponding stile and for this purpose a spring 31 is interposed between the nut 33 and the bottom 35 of its retaining holder or cage 34. This spring, of course, presses the channel toward the stile and presses the nut 33 in the opposite direction. The thrust of the pressure against the nut 33 is taken by an enlarged collar 4D formed on the pin 3l, this collar bearing against a wear plate 4| which is set into the outer face of the stile around the opening 32 and through which the pin 3l extends. This plate is preferably removably secured in position by screws or in any other suitable manner and in order to permit the pin 3| to be withdrawn the hole 32 is enlarged at its outer end, as indicated at 42, the enlarged collar 4E! of the pin being disposed within this enlarged portion of the hole and the enlarged portion of the hole being sufiiciently deep so as to permit complete withdrawal of the pin 3l from the channel 3D.

To the inside of each of the channels' 30 is also welded or otherwise secured a pair of abutment members which are of angular form and present an abrupt downward face. The purpose of these abutment members is to catch the ring 46 at the lower end of the sash cord or chain 41, each of these chains being, of course, hung upon the corresponding pulley I1 and suspending a counter weight 48.

In order to retain the ring 45 between the pair of abutment members 45 a second smaller channel 5U is disposed within eachof the main channels 30, the back of each of the smaller channels 50 preferably bearing against the edges of the abutment members 45 and also the ends of the flanges 36 of the retaining cage 34 for the nut 33 and the edges 5I of each of these channels 50 terminating along the edge of the flanges of the main channel 3l] in which the secondary channel 50 is disposed. The nanges of the channels 30 and 50 are preferably permanently secured together and in order to permit of readily attaching and detaching the sash cord, each of the inner channels 50 is preferably slotted at one end, as indicated at 52 to a point adjacent the abutment members 45 and below these abutment members 45 the inner channel 50 is provided with a hole 53. This hole is of sufcient size so. that the chain. 41l can be dropped between the abutment members 45;'and drawn out through the hole 53, the ring 41 being thereafter attached to the end of the chain and drawn backwardly through the hole 53 into latching engagement with the abrupt faces of the abutment members 45, as best illustrated in Fig. 6. Ihat pair of anges of the channels 30 and 50 on the inside of the sash are held together by a facing strip of'sheetu metal 54, one edge of which is turned to embrace the ends of these flanges and is pressed into rm engagement therewith soas to lock the flanges together., ThisV facing strip 54 extends alongV the; flange ofthe channel 3D and at its lower end is extendedA beyondA the; channel 30 and along the inside'face ofthe corresponding stile of the window frame. This extended. part 55 is formed; at its vertical; edge to, provide; a laterally extending lip- 55 which, when. the sashA is disposed in a vertical posit-ion, tightly nts within a vertical groove 51 in the lower partv of the corresponding windowy stile. The extending part 55 and the groove 511 of course, extend less than half way up thev sash so as not to. interfere with the upper end of the sash being: swung inwardly although, of' course, preventing the lower end ofl the sash from being: swung in.- wardly and providing a weather seal for the lower end of the sash. The two flanges of each of the channels 30 and 50 on the outside of the; Window are similarly held together by the reversely bent edge of a face plate which extends the full height of the channels 30 and 5t and the upper portion 6l of which is extended over the outside of the correspondingV stile and provided with a lip 62 which enters a vertical groove 53 in the upper part of the outside face of the corresponding stile when the sash is swung to a vertical position. It will be appreciated that the lip 62 of the outside face plate 60 provides a weather seal for the upper half of the sash and that the lip 56 of the inside face plate 54 provides a weather seal for the lower half of the sash so that adequate weather proofing is provided the full height of the sash. It will also be appreciated that the spring 31 draws the corresponding stile of the sash and the adjacent channel 30 of the carrier into firm engagement with one another so as to additionally render the window weather proof and further this Spring in no way tends to crowd the flange of the carrier into the vertical grooves of the jambs so that the carriers and sash are at all times freely slidable in the. grooves of the jambs. It will also be appreciated by turning the edges of the face plates 54 and 60 around the edges of the channels 30 and 5U that not only are the different parts of the carriers secured together but also that smooth runners are provided for the carriers which assist their movement up and down the grooves in the jambs.

Inasmuch as it is desirable to employ standard sash in windows embodying the invention it is undesirable to have portions of the check rails 24 and 25 extend beyond the carriers so as to ll the space between the corresponding carriers of the upper and lower sash. Therefore filler pieces 64, preferably made of sheet metal, are preferably' secured to the lower inside ends of the carriers for the upper sash and to the outside upper faces of the carriers for the inside lower sash. These filler pieces engage one another when the check rails 24 and 25 engage one another, as best illustrated in Fig. 8, and, in effect, merely form continuations of the check rails.

It is also desirable to block the ends of the space 65 between the channels 30 and 5U and for this purpose the space is blocked off by means of blocks 66 inserted in the ends of this space and held in place in any suitable manner as by nails or screws extending through the channel 30 into each of these blocks.

From the foregoing it is apparent that this invention provides a very simple double hung window in which the sash slide vertically and are counter-weighted and at the same time are easily swung about the pivot pins 3l so as to obtain draftless ventilation and so as to facilitate washing of the windows since each of the sash can be swung to a horizontal position and the outside of the window readily cleaned from the inside of the budding. It win also be noted that the sash are drawn tightly against their carriers by the springs 3l so as to provide weather tightness and that further weather sealing is provided by the lips 56 and 62 engaging tightly in the vertical grooves provided in the inside of the lower part of the sash and the outside of the upper part of the sash, these lips not in any way interfering with the free swinging of the sash to a horizontal position. It will further be observed that all stops are eliminated and that by providing grooves in the jambs for the runners of the carriers a double weather-tight protection is provided which eliminates the necessity of weather stripping between the carriersy and the jambs.

The elimination of the usual stops is permitted because in hanging the sash the carriers can first be mounted in their grooves in the jamb, the sash placed between the carriers and the pivot pins 3| then moved outwardly and screwed into the nuts 33. Dismounting of the sash can, of course, be

accomplished with equal facility by merely withdrawing the pivot pins 3l and removing the sash, after which the carriers can easily be disconnected from the sash cords or chains. The present invention therefor provides a very simple window which is weather-tight without auxiliary stripping, which can be easily hung or dismounted and which has the advantage of both the sliding and the pivotal mounting for the sash and at the same time can be produced at very little added cost as compared with the usual double hung window.
